IMPROVEMENT IN 'rmrr-couprmes.

Specification forming part of Letters Patent No. 148.0] 1, datedFebruary 24, 1674; application filed April 19, 1873.

To allwhom it may concern: 4

Be it known that I, LEVERETT DWVAIa REN, of W'ethersfield, in the countyof Hartford and State of Connecticut, have invented a new and valuableImprovement in Clip and Thin-Fastening; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawingsmaking a part of this specification, and to the letters and figures ofreference marked thereon.

Figure l of the drawings is a representation of a side View of mythill-coupling. Fig. 2 is a top view of the same. Fig. 3 is a sectionalview, and Figs. 4, 5, and 6 detail views, of the PHI-c.

This invention has relation to chill-couplings; and it consists in theconstruction and novel arrangement of the hooked end of thecouplingiron,threaded for the'reception of a nut. The object of this invention is toprovide a durable and easily-adjusted thill-coupling, which may beconstructed without using rubber.

In the accompanying drawings, the letter A designates the coupling-iron,perforated at a a for the passage of the ends of the clip. B indicates ahook, forming a part of the coupling-iron. Dovetail flanges b areprovided on each side of the coupling-iron, to serve as guides for theslide. D indicates the roller, having a square opening through itscenter, and a peripheral groove bounded by flanges c, which embracethesides of the inner wall of the hook B, and the sides of the slide at itsforward edge. E designates the slide. This has flanges d at its base tofit the guides b. of the coupling-iron. It is perforated at its upperportion for the passage of the straight threaded portion 0 of the hook,a nut, 9, being screwed on this portion, and bearing against the rearwall of the slide. On its forward or inside edge the slide E is providedwith the concave circular projection or tongue k, which is designed tofit the groove of the roller when the slide is pressed home. The base ofthe slide is a solid block, extending somewhat to the rear, as at m,and, when in position, abutting against the bearing-face o of the clip2. G indicates the thill-iron, and

u the square bolt by which it is secured to the roller of the coupling.This coupling is readily adjusted and easily tightened to preventrattling.

What I claim as new, and desire to secure by Letters Patent, is

In a thill-coupling, the removable slide E, having the flanges (1 at itsbase to fit the guides I), the concave circular tongue k to fit thegroove of the roller D, and perforated at its upper portion for thepassage of threaded portion 6 of the hook A, substantially as and forthe purpose specified. V

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
